What is the thing that is in some home bathrooms and is like a ladder (you can see it in the picture)? What is it called? What is it there for?
That ladder like thing in a bathroom area is a combination towel rack and heater. The heater is generally used to warm and/or dry the towels but can also lend to taking the chill off the bathroom.
It has been my experience to see those mostly in Europe and I cannot actually remember ever seeing one installed in the US but I am sure they are used here.
It's a towel warmer. You hang the towel like on a standard bar, and the heat elements keep the towel warm all over.
It could also be used for hanging clothes to dry if not wanting to use dryer, I've seen clothes rack mounted to bathroom wall in all sorts of design, it's best way to " line" dry clothes especially if you live in a apartment building with limited space, city living and eco friendly if access to outdoor line is impossible,
